How do you prevent restless leg syndrome?

Quinine for RLS . It's the quinine itself that helps RLS (whether its in capsules or some other form, not just quinine water). Quinine has been used for years (since WW II) for nocturnal leg cramps....

Yes they can just like humans. My dog has it.

noI HAVE to improve upon this answer! NO, RLS in itself is not deadly, but severe sleep deprivation that comes along with it can be very deadly. RLS is connected to heart disease, diabetes, drowsy...

Diet is one factor that can prevent symptoms of RLS. A helpful diet will include an adequate intake of iron and the B vitamins, especially B12 and folic acid.

no it is annoying but not fatal
